Abstract: A Schottky barrier diode (SBD) is provided, which improves electrical characteristics and optical characteristics by securing high crystallinity by including an n-gallium nitride (GaN) layer and a GaN layer which are doped with aluminum (Al). In addition, by providing a p-GaN layer on the Al-doped GaN layer, a depletion layer may be formed when a reverse current is applied, thereby reducing a leakage current. The SBD may be manufactured by etching a part of the Al-doped GaN layer and growing a p-GaN layer from the etched part of the Al-doped GaN layer. Therefore, a thin film crystal is not damaged, thereby increasing reliability. Also, since dedicated processes for ion implantation and thermal processing are not necessary, simplified process and reduced cost may be achieved.

Abstract: A power device manufacturing method is provided. The power device manufacturing method may perform patterning of regions on which a source electrode and a drain electrode are to be formed, may regrow n+-gallium nitride (GaN) and p+-GaN in the patterned regions and thus, a thin film crystal may not be damaged. Also, a doping concentration of n+-GaN or p+-GaN may be adjusted, an ohmic resistance in the source electrode region and the drain electrode region may decrease, and a current density may increase. The power device manufacturing method may regrow n+-GaN and p+-GaN at a high temperature after an n-GaN layer and a p-GaN layer are patterned. Accordingly, a thin film crystal may not be damaged and thus, a reliability may be secured, and an annealing process may not be additionally performed and thus, a process may be simplified and a cost may be reduced.

Abstract: A method for establishing an interface between a host and a plurality of memory devices of a system that utilizes a Multimedia Card (MMC)/Secure Digital (SD) protocol according to an interleaving scheme. A host sequentially transmits a first sequence of commands and data to a system bus in order to allow a first memory device among the memory devices to perform a first operation. The host then transmits a second sequence of commands and data to the system bus to allow a second memory device among the memory devices to perform a second operation after transmitting the first sequence of commands and data.
